GA-73PVM-S2H - cpu is underclocking itself?

I just recently installed Windows XP on my new machine and I noticed that when launching the EasyTune5 that the current speed is 2666.00 mhz but the current says 1975.00 and fluctuates a little bit. My motherboard is a GIGABYTE GA-73PVM-S2H Once in a while it will jump to 2666.00 but them back down. I did use the @Bios and updated the bios to see if that would fix the issue and so far it dint seem to. I also went into the Bios and reset it to factory defaults. Is there something that I need to change or an update that I need? Or is this something with my CPU?

I also have installed and verified all drivers installed from the cd. Please let me know what you can suggest.

Thanks,
Jake
